Description

  The present invention relates to a refrigerator provided with an atomization device for maintaining a storage room space for storing fresh products such as vegetables in a high humidity environment.

  In recent years, particularly in refrigerators, refrigerators have been proposed in which the inside of a vegetable container in the refrigerator is humidified to maintain the freshness of vegetables.

  As a conventional humidification method, there is a method using a humidifier using a Langevin type ultrasonic vibrator as an atomizer (see, for example, Patent Document 1).

  FIG. 7 shows a side sectional view of a refrigerator provided with a conventional ultrasonic atomizing device described in Patent Document 1. As shown in FIG. FIG. 8 is an enlarged view showing a main part of the ultrasonic atomizer.

  As shown in FIG. 7, the refrigerator compartment 2 is arrange | positioned in the uppermost part of the storage space inside the refrigerator main body 1 which consists of heat insulation boxes, and the vegetable compartment 3 is provided in the downward direction via the partition plate 4. As shown in FIG. Below the vegetable compartment 3, an ice storage compartment 5 and a temperature switching compartment (not shown) are arranged side by side through a heat insulating partition wall, and a freezer compartment 6 is arranged at the bottom.

  On the back of the refrigeration space and the freezing space, there are provided a refrigeration cooler 7, a refrigeration cooler 8, and blower fans 9 and 10 located in the vicinity of each cooler. A compressor 11 for supplying refrigerant to the cooling units 7 and 8 is installed.

  The refrigerator compartment 2 is provided with a shelf on which food is placed and a supply tank 13 for supplying water to an automatic ice making device 12 provided in the ice storage compartment 5. A suction duct 17 for guiding cold air to the vegetable compartment 3 is also configured.

  The vegetable room 3 is provided with a container 15 for storing vegetables and an upper container 16 having a small capacity so as to be divided and stored in the upper part thereof, and is a high humidity means in the vegetable room 3 on the lower surface of the partition plate 4. A humidifier 20 is provided.

  About the refrigerator comprised as mentioned above, the operation | movement is demonstrated below.

  Cold air around the coolers 7 and 8 is circulated through the refrigeration space and the freezing space by the blower fans 9 and 10. The cold air circulated in the refrigerator compartment 2 is introduced into the suction duct 17 as shown by the arrow, and is circulated through the suction duct 17 so that it is cooled by the natural drop of the cold air from above by the cooled partition plate 4 and is sucked in. The vegetable room 3 is cooled by introducing the cold air flowing through the duct 17 into the vegetable room 3.

  The humidity inside the vegetable compartment 3 is detected by a humidity sensor (not shown), and when the humidity is lower than a predetermined value, the mist-like water is sprayed inside the vegetable compartment 3 to increase the humidity. Freshness can be maintained.

  Next, the humidifier 20 using a Langevin type ultrasonic transducer will be described with reference to FIG.

  In general, the Langevin type vibrator alone is difficult to generate only fine mist, and therefore, a means capable of classifying, that is, adjusting the particle diameter by a fine pore filter or the like is used in combination.

  In FIG. 8, the humidifier 20 provided on the lower surface of the partition plate 4 has a large diameter in contact with the piezoelectric element 23, the electrode 25, and the end face of the piezoelectric element 23 in the storage case 26 provided on the ceiling of the water storage tank 22. A Langevin type ultrasonic transducer 21 composed of a horn 21a having a small diameter from the head toward the tip is provided, and a mesh is formed by forming a small interval at the mist generation site of the horn tip 21a of the ultrasonic transducer 21. A filter 27 is arranged.

  When the Langevin type ultrasonic vibrator 21 is operated, the moisture in the horn tip 21 a is atomized by passing through a small hole formed in the mesh filter 27 and sprayed into the vegetable compartment 3 as a mist 24.

  The mesh filter 27 causes clogging due to the scale due to the mist generating action that repeatedly operates over a long period of time, and as a result, it becomes difficult to generate mist, so that the position of the facing surface is movably provided. For example, the filter 27 is formed in a disk shape and is rotatable about the shaft 27a. The filter surface facing the horn tip 21a, which is the mist generation site of the Langevin type vibrator 21, is connected to the shaft 27a from the horn tip 21a. It corresponds so that it may come off.

  Then, before the time when the small holes of the mesh filter 27 are clogged with the scale due to the mist generating action for a predetermined period, the new surface of the mesh filter 27 is rotated by a predetermined angle around the shaft 27a, thereby making the Langevin type vibrator It is made to oppose 21.

By moving the position of the mesh filter 27, it is possible to spray mist-like fine particles over a long period of time without clogging, so that the mist can be stably humidified. The freshness of vegetables can be maintained without water rot caused by excessive water supply.
JP 2005-337694 A

  However, in the conventional configuration described above, in order to move the position of the mesh filter 27 for classifying mist, the shaft 27a and a device for rotating the shaft 27a are separately required in the humidifier 20, and the humidifier 20 Since the configuration is complicated and the device itself is large, installing it in the storage room of a household refrigerator where a large capacity is required reduces the storage capacity of the storage room by pressing the storage space volume of the storage room. Since it became small and contrary to the needs of consumers, it had the problem that it was difficult to actually mount it in a refrigerator.

  Further, in the refrigerator, when spraying directly into the storage chamber, if the spray amount is large and excessive spraying occurs, water rot of stored items such as vegetables in the storage chamber occurs or condensation occurs in the storage chamber. There was a problem.

  In addition, while there is a demand for spraying mist over a desired range or a wide range, the above-described conventional configuration requires a considerable improvement in order to satisfy the demand.

  The present invention solves the above-mentioned conventional problems, and is installed in a storage room of a refrigerator for home use to prevent condensation in the storage room due to excessive spraying even when spraying mist directly into the storage room. It is an object of the present invention to maintain freshness of food and the like over a long period of time by spraying fine particle mist stably in a range.

In order to solve the above conventional problems, the refrigerator of the present invention includes a heat insulating box having a storage chamber, an atomization device for atomizing a liquid and spraying the liquid into the storage chamber, and a mist generated by the atomization device. Spray amount adjusting means for reducing the amount, and restricting means for restricting the direction of the mist atomized by the atomizer, the restricting means at least part of the mist sprayed from the spray device. An inclination provided integrally from a container for storing stored water on the storage chamber side of the atomizer at an angle to be blocked.
A swash plate is used to supply the liquid to the spray tip located above the upper end of the tilt plate by the surface tension action between the stored water below the spray tip and the container .

  Thus, even when the mist is directly sprayed into the storage room of the refrigerator and sprayed directly into the storage room, by providing a spray amount adjusting means for reducing the spray amount of the mist after atomization into the storage room, It is possible to prevent excessive spraying, and further, by controlling the direction to a desired range and spraying fine particle mist, it is possible to improve the diffusibility of mist and improve the freshness of vegetables etc. Become.

  The refrigerator of the present invention is capable of stably spraying the fine particle mist in a desired range even when spraying mist directly into the storage chamber, and thus maintaining the freshness of stored items such as vegetables. It is possible to provide a high-quality refrigerator that further enhances the quality.

The invention according to claim 1 is a heat insulation box having a storage chamber, an atomizing device for atomizing a liquid and spraying the liquid into the storage chamber, and a spray amount adjustment for reducing the amount of mist generated by the atomizing device.

Therefore, it is possible to provide a high-quality refrigerator in which the freshness of stored items such as vegetables is further improved.

  In addition, since the mist generated by the atomizer can be sprayed in a regulated direction, spraying according to the application, such as direct spraying on stored items or indirect spraying avoiding direct spraying on stored items, can be performed. It becomes possible.

In addition , it is possible to secure the spray reach distance to the far side in the storage room, and further, because the regulation means can be regulated on the side closer to the storage room because it is located on the side of the storage room than the internal partition, The direction of the mist sprayed from the atomizer can be regulated more reliably, and the regulating means also has a function of a spray amount adjusting means for blocking the mist to be sprayed. The amount of spray can be controlled, and the mist diffusibility can be improved by spraying an appropriate amount of fine mist by regulating the direction to a desired range, and improving the freshness of vegetables and the like Therefore, it is possible to provide a high-quality refrigerator in which the freshness of stored items such as vegetables is further improved.

  In addition, since the regulating means regulates the direction by blocking a part of the mist, it can be realized with a simple configuration without requiring a complicated drive device and the like, so that it can be mounted on a household refrigerator and has a compact configuration. It is possible to provide a highly reliable atomizing device that does not require a complicated configuration such as a driving device, saves material and does not burden the environment, and reduces the possibility of malfunction or failure. it can.

  Further, since the regulating means functions as the spray amount adjusting means by blocking a part of the mist, the regulating means and the spray amount adjusting means can be provided with a simpler structure, and the drive device and the like are complicated. Therefore, the possibility of malfunction or failure can be reduced, and a more reliable atomization apparatus can be provided. Accordingly, it is possible to provide a refrigerator that can perform humidification necessary for maintaining the freshness more stably and maintain the freshness of fresh food such as food over a long period of time.

Moreover , the direction of the mist sprayed with a compact and simple configuration can be regulated by the inclined plate provided opposite to the spraying direction as the regulating means, and further the amount of sprayed mist after atomization can be controlled by the same inclined plate. Since it becomes possible to reduce, since the inclined plate also has a function as a spray amount adjusting means, both the regulating means and the spray amount adjusting means can be realized with a simple configuration.

  In this way, since the inclined surface by the inclined plate functions as the regulating means and the spray amount adjusting means without requiring a complicated drive device or the like, it should be compact and simple to the extent that it can be mounted on a household refrigerator. In addition, since a complicated configuration such as a driving device is not required, it is possible to provide a highly reliable atomizing device that saves material and does not burden the environment and reduces the possibility of malfunction or failure.

  As a result, even when the mist is sprayed directly into the storage chamber, the amount of mist spray is adjusted to prevent excessive spraying, and the mist spraying direction is regulated to stabilize the fine particle mist within a desired range. A refrigerator that can maintain the freshness of food and other foods over a long period of time, even in household refrigerators that are premised on long-term use. It becomes possible to provide.

According to a second aspect of the present invention, in the first aspect of the present invention, the regulating means further includes a hollow nozzle provided on the storage chamber side of the atomizing device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking as an example a case where the liquid is water. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a side cross-sectional view of the refrigerator according to Embodiment 1 of the present invention. FIG. 2 is a side sectional view of the ultrasonic atomizing device for a refrigerator according to Embodiment 1 of the present invention.

  In FIG. 1, the refrigerator 101 is partitioned from the top into a refrigerator compartment 103, a switching chamber 104, a vegetable compartment 105, and a freezer compartment 106, which are storage compartments, by partitions 102a, 102b, and 102c. The doors 107, 108, 109, and 110 are closed so that there is no inflow of outside air.

  A vegetable room storage container 111 is installed in the vegetable room 105, and food is stored in a space where the humidity is about 80% RH or more (when food is stored) and the temperature is cooled to 4 to 6 ° C. On the back side of the vegetable compartment 105, an internal partition 113 for dividing the air passage 112 and the vegetable compartment 105 is provided. The internal partition 113 is provided with a Langevin type ultrasonic atomizer 114 as an atomizer. The tip of the ultrasonic atomizer 114 is directed toward the vegetable compartment 105 (storage container 111), which is a storage room.

  Next, the ultrasonic atomizer 114 will be described.

  In FIG. 2, the ultrasonic atomizer 114 installed in the internal partition 113 is attached to the main body cover 203 and faces the spray opening 202 provided on the front wall. The main body cover 203 also serves as a container for storing the stored water 201 therein. The ultrasonic atomization device 114 is in contact with the piezoelectric element 204, the electrode 205, and the piezoelectric element 204, and has a Langevin type ultrasonic pendulum 206 having a spray tip 207 that gradually decreases in diameter as it moves away from the end face. The spray tip 207 is disposed so as to pass through a through hole 203 a provided in the rear wall and to be inside the spray opening 202. In addition, a seal member 203b having a buffer property and water tightness such as an O-ring is provided at the periphery of the penetrating portion of the spray tip 207, and the stored water 201 is configured not to leak to the ultrasonic transducer 206 side. .

  Further, on the outside of the main body cover 203 below the spray opening 202, there is provided an inclined plate 208 that is inclined upward facing the spray direction. The inclined plate 208 is a regulating means that regulates the direction of the mist atomized by the ultrasonic atomizer 114 that is an atomizer. The inclined plate 208 serving as the restricting means is provided on the vegetable compartment 105 side which is the storage room from the spray tip 207 where the mist generated by the ultrasonic atomizer 114 is sprayed, and further than the internal compartment 113 of the vegetable compartment 105. It is set as the structure located in the vegetable compartment 105 side, and the inclination board | plate 208 which is a control means controls the spraying direction of mist by interrupting | blocking at least one part of the mist sprayed from the said atomizer. At this time, the inclined plate 208 extends into the vegetable compartment 105.

  Further, the ultrasonic transducer 206 and the piezoelectric element 204 are bonded and fixed, and the vibration generated by the piezoelectric element 204 is amplified so as to have a maximum amplitude at the spray tip 207.

  The stored water 201 in the main body cover 203 is attached to the spray tip 207 of the ultrasonic atomizer 114 by the surface tension action, and the water attached by the vibration of the spray tip 207 is misted. Sprayed. Therefore, the lower side of the spray opening 202 is disposed so as to maintain a water level at which the surface tension acts.

  Although the water level is such that surface tension is generated at the spray tip 207, the stored water 201, which is water for spraying, is held on substantially the same surface slightly below the lower end of the spray tip 207 below. .

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In the case of a refrigerator, cold air is distributed to the refrigeration room 103, the switching room 104, the vegetable room 105, the freezing room 106, etc. by a stirring fan (not shown), etc., and controlled to be turned ON / OFF so as to maintain a predetermined temperature. It is common. The vegetable room 105 is adjusted so that the temperature becomes 4 ° C. to 6 ° C. by ON / OFF operation such as cold air distribution and heating means.

  Then, when the door 109 is closed horizontally after the door 109 is pulled out horizontally and vegetables are put into the vegetable compartment storage container 111, the door opening detection means (not shown) detects the closed state, and the ultrasonic atomizer 114 starts mist spraying, and humidifies the inside of the vegetable compartment 105.

  In the ultrasonic atomizer 114, the water stored in the main body cover 203 is attached to the spray tip 207 by the surface tension action. Then, the piezoelectric element 204 is operated in a state where desired water necessary for atomization is supplied to the spray tip 207, and the ultrasonic transducer 206 is vibrated so that the spray tip 207 is amplified to have the maximum amplitude. The energy of the tip part is transmitted to water, and the water is split to generate mist. The mist is blown in the direction of the spray opening 202 and sprayed into the vegetable compartment 105.

  As the moisture supply to the vegetable surface for increasing the humidity in the vegetable chamber 105 and maintaining the freshness, a fine mist having a particle size of 20 μm or less is preferable, but a large mist having a particle size larger than that is also generated.

  At this time, the fine mist advances a lot in the forward direction, that is, in the direction A indicated by the arrow. On the other hand, a large mist having a large particle size has a large weight and therefore flies in a direction closer to the surface of the water 201. Utilizing this characteristic, large mist is collided with the inclined plate 208 to prevent spraying from the spray opening 202 to the outside. Therefore, the inclined plate 208 is positioned at a height at which the inclined plate 208 can operate.

  For example, the upper end height H of the inclined plate 208 from the lower end of the main body cover 203 is adjusted between the center of the spray tip 207 and the lower side of the spray opening 202.

  By positioning in this way, it is possible to regulate the downward spraying of the mist to be sprayed, taking advantage of the characteristic that a large amount of mist having a large particle size is included below as described above, and the particle size is relatively small. The amount of spraying can be reduced with a large mist. Therefore, the inclined plate 208 is a regulating unit that regulates the direction of mist spraying, and is also a spray amount adjusting unit that reduces the spray amount of atomized mist, and has a function that combines the regulating unit and the spray amount adjusting unit. It can be realized with one member.

  In addition, as in the present embodiment, the water 201 that is the storage water for spraying is provided on substantially the same plane as the lower end of the spray tip 207 below only to the extent that surface tension is generated in the spray tip 207. Therefore, the amount of mist sprayed downward from the spray tip 207 is reduced by the presence of the stored water as compared with the case where the stored water is not present or is located below. Since it has a function as a spray amount adjusting means, it can be said that the stored water is also a spray amount adjusting means in the present invention. Similarly, since the mist spraying downward is regulated by the stored water, it can be said that the stored water is also a regulating means for regulating the direction of the mist spray in the present invention.

  With such a configuration, even if the atomization amount adjusting means and the regulating means are installed in the storage room of a household refrigerator where a larger capacity is required, the storage room can be stored without pressing the storage space volume of the storage room. Therefore, it is possible to provide a refrigerator equipped with an easy-to-use atomizing device that has a large storage room capacity that meets consumer needs and high freshness.

  As described above, a complicated driving device is not required, and the inclined surface by the stored water and the inclined plate functions as a regulating means and a spray amount adjusting means, so that it is compact and simple enough to be mounted on a household refrigerator. A highly reliable atomization device that does not require a complicated structure such as a drive unit, and that saves material and does not place a burden on the environment, and reduces the possibility of malfunction or failure. Can be provided.

  In addition, since water can be supplied directly from the stored water 201 to the spray tip 207 without using a dedicated member, water can be supplied with a simpler configuration. It is possible to realize a highly reliable atomization apparatus with a low possibility of a malfunction or water outage.

  Furthermore, the vegetable room 105 of the refrigerator is set to a higher temperature than other storage rooms, but in order to adjust the temperature, in addition to supplying cold air, a heating source such as a heater is often used. Although the temperature change in the chamber is relatively large, even when the atomizing device is provided in a storage room having such a large temperature change, when water is supplied using the surface tension of the stored water 201, the stored water 201 Since the heat capacity is large, it is not easily affected by changes in the outside air temperature, and since the spray tip 207 always conducts heat with the stored water 201, the water adhering to the spray tip is also less susceptible to temperature and more stable spraying. The amount can be secured.

  For example, in the case of a method of sucking up stored water using a water retaining material, which has been common in the past, or a method of supplying water using a supply path for supplying water to the spray tip, the heat supply on the supply path There was a concern that the temperature change of the water at the tip of the spray was likely to be affected, resulting in a large unevenness in the amount of atomization.

  Further, since the spray tip is connected to the stored water 201 as in the present embodiment, the heat capacity is greatly increased, so that the spray tip due to the influence of temperature change such as heat generation in the ultrasonic pendulum 206 is increased. The temperature change can also be reduced, and more stable spraying can be realized.

  As a result, even when the mist is sprayed directly into the storage room, the amount of mist that tends to cause dew condensation can be further reduced by adjusting the amount of mist sprayed, and the amount of large mist that tends to cause condensation can be reduced. There is an extraordinary effect that an atomizing device having a stable spray amount that is resistant to temperature changes can be realized. Also, by regulating the direction of mist spraying, it is possible to stably spray fine particle mist in a desired range, so humidification necessary for maintaining freshness can be performed more stably, and household refrigerators that are premised on long-term use However, it is possible to provide a refrigerator capable of maintaining the freshness of fresh food such as food over a long period of time.

  That is, the inside of the vegetable compartment 105 can be efficiently humidified, and the condensation in the vegetable compartment 105 due to the large mist and the water rot due to excessive water supply to the vegetable surface are suppressed, and the highly diffusible fine mist. Can maintain the freshness of the vegetables.

  As described above, in the first embodiment, the ultrasonic atomization device 114 that is an atomization device is installed in the vegetable room 105 that is the storage room of the refrigerator, and even when the mist is sprayed directly into the vegetable room 105. By providing the inclined plate 208 which is a spray amount adjusting means for reducing the spray amount of the mist after atomization, it is possible to prevent excessive spraying of the mist and further regulate the direction to a desired range and fine particles Since it is possible to spray mist, it is possible to improve the diffusibility of mist and improve the freshness of vegetables and so on. A refrigerator can be provided.

  In addition, since it is provided with the inclined plate 208 which is a regulating means for spraying the mist generated by the atomizing device in a regulated direction, indirect spraying avoiding direct spraying on the stored item or direct spraying on the stored item, etc. Spraying according to the application is possible.

  In the first embodiment, the number of parts can be further reduced by reducing the spray amount by inclining the wall surface below the spray opening 202 facing the spray direction of the main body cover 203 upward. The present invention can be implemented with a material-saving and environment-friendly configuration.

  In the first embodiment, since the spray tip 207 is configured inside the spray opening 202 provided in the main body cover 203, the stored item touches the spray tip 207 which is a vibration part and performs a spray operation. It is possible to reduce the possibility of malfunction or failure of the atomizer by preventing foreign matter such as vegetables from being mixed. Furthermore, since it can prevent that a user's hand touches accidentally, a user's safety | security can be improved.

  Moreover, in this Embodiment 1, since the large mist which collided with the inclination board 208 flows down on the inclination board 208, and can collect | recover in the main body cover 203 again, the stored stored water 201 is utilized efficiently. be able to.

  Although the atomizing device is a Langevin type ultrasonic atomizing device, a mist can be sprayed, for example, a disk type ultrasonic atomizing method or an electrostatic atomizing device may be used.

  In the present embodiment, the inclined plate 208 is used as a member having the function of both the regulating means and the spray amount adjusting means, and the stored water 201 also has the function of serving as the regulating means and the spray amount adjusting means. However, even when the inclined plate is not installed, it is possible to have a function as a desired spray amount adjusting means by adjusting the storage method of the stored water 201 and the dimensions of the storage container. By regulating the mist spray to the lower side by adjusting the storage method and the dimensions of the storage container, it becomes possible to have a function as a regulating means for regulating the direction of mist spray. The object of the present invention can be achieved with a simple configuration.

(Embodiment 2)
FIG. 3 is a side sectional view of the ultrasonic atomizer of the refrigerator according to Embodiment 2 of the present invention. FIG. 4 is a cross-sectional plan view illustrating the mist scattering and the air flow state of the ultrasonic atomizer of the refrigerator according to the second embodiment of the present invention. Here, the same constituent elements as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 3, a hollow nozzle 209 is installed outside the spray opening 202 provided in the main body cover 203 of the ultrasonic atomizer 114, and the outlet 210 thereof faces the vegetable compartment 105. . This nozzle 209 is a regulating means for regulating the direction of the mist atomized by the ultrasonic atomizer 114 which is an atomizer. Nozzle 209 which is a regulating means is provided on the vegetable compartment 105 side from the spray tip 207 where the mist generated by the ultrasonic atomizer 114 is sprayed, and further on the vegetable compartment 105 side than the compartment 113 of the vegetable compartment 105. The nozzle 209 serving as a regulating means regulates the spraying direction of the mist by blocking at least a part of the mist sprayed from the atomizing device. At this time, the nozzle 209 extends into the vegetable compartment 105. The lower surface of the nozzle 209, that is, the surface facing the spraying direction formed below the spray opening 202 is inclined upward. Therefore, the nozzle 209 has a configuration in which the area through which mist passes gradually decreases toward the outlet 210.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  In addition, about the operation | movement and effect | action of a control means, the description is abbreviate | omitted about the part similar to Embodiment 1. FIG.

  The mist generated from the spray tip 207 is a surface inclined above the lower surface forming the nozzle 209, and the spray amount is reduced by blocking a part of the sprayed mist.

  The mist that has passed through the nozzle 209 is sprayed from the outlet 210 of the nozzle 209 to have a directivity as shown in FIG. Therefore, it is possible to efficiently supply moisture to the vegetable surface to be kept fresh.

  In addition, since the spray tip 207 is installed in the vegetable compartment 105, a sufficient spray speed can be ensured, so that spraying to a further distance is possible and diffusibility of mist particles can be improved. it can.

  As described above, in the second embodiment, the nozzle 209 is used as a regulating unit that regulates the direction of mist spraying, and also functions as a spray amount adjusting unit that reduces the spray amount of atomized mist. The function having both the regulating means and the spray amount adjusting means can be realized by a single member.

  As a result, the storage capacity of the storage room can be reduced without squeezing the storage space volume of the storage room even if the atomization amount adjusting means and the regulation means are installed in the storage room of a household refrigerator where a large capacity is required. Therefore, it is possible to provide a refrigerator provided with an atomizing device that is easy to use and meets consumer needs.

  Therefore, since the inclined surface by the inclined plate functions as the regulating means and the spray amount adjusting means without requiring a complicated driving device or the like, it can be made compact and simple to the extent that it can be mounted on a household refrigerator. In addition, since a complicated configuration such as a driving device is not required, it is possible to provide a highly reliable atomizing device that saves material and does not place an environmental load and reduces the possibility of malfunction or failure.

  Furthermore, since the outlet 210 can be set in an arbitrary direction depending on how the nozzle 209 is installed, the directivity can be given to the fine mist sprayed from the outlet 210, and the freshness of the target range can be maintained. Necessary humidification can be stably performed, and the freshness of foods and the like can be maintained over a long period of time.

  Furthermore, by using the hollow nozzle 209 as the regulating means, the direction of the mist spray can be regulated with a simple configuration in almost all directions, up, down, left and right, so that the spray from the nozzle has directivity. It is possible to concentrate spraying to the necessary places.

  In addition, since the opening area of the outlet 210 which is the tip of the nozzle 209 on the vegetable chamber 105 side is set to be smaller than the area of the spray opening 202 which is the opening on the ultrasonic atomizer 114 side, In the direction of spraying, the direction is controlled in a simple configuration in almost all directions, up, down, left, and right, and intrusion of foreign matter from the outlet 210, which is the opening inside the nozzle 209, can be suppressed. Since the finger is prevented from touching the spraying tip 207 and the vibration part of the chemicalizing device 114, the safety of the user can be improved, and further, foreign matter such as vegetable waste can be prevented from entering. The reliability of the atomizer can be increased.

  Further, in Embodiment 2, by making the nozzle 209 detachable, the inside of the main body cover 203 can be easily cleaned, and the nozzle 209 can be easily cleaned and replaced, resulting in long-term use. It is possible to prevent the classification function from being deteriorated due to deterioration.

  Although the atomizing device is a Langevin type ultrasonic atomizing device, a mist can be sprayed, for example, a disk type ultrasonic atomizing method or an electrostatic atomizing device may be used.

(Embodiment 3)
FIG. 5 is a side cross-sectional view of the ultrasonic device of the refrigerator in the third embodiment of the present invention. FIG. 6 is a cross-sectional plan view showing the mist scattering and the air flow state of the ultrasonic device of the refrigerator in the third embodiment of the present invention. Here, the same constituent elements as those of the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 5, the slit 211 which is an opening part is provided in the side surface which is the wall surface of the nozzle 209 in the part in contact with the main body cover 203, and is provided on both side surfaces in this embodiment.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The mist generated from the spray tip 207 is reduced to a mist having a desired range and spray amount, with the spray amount being reduced centering on the surface inclined particularly above the lower surface of the nozzle 209 which is the regulating means and the spray amount adjusting means. Classified. Since the operation and action of the nozzle 209 are the same as those in the first or second embodiment, description thereof is omitted.

  In the nozzle 209, an air flow is generated by fine mist that is classified and continuously sprayed. This state will be described with reference to FIG.

  In the nozzle 209, when the air goes back and forth between the main body cover 203 and the outside only by the outlet 210 of the nozzle 209, the amount of air flowing out from the main body cover 203 and the amount of air that is balanced with it will flow in. As indicated by the broken line arrows in FIG. 4, a circulating vortex (short circuit) is generated in the nozzle 209. This air flow is limited because the direction of the fine mist scattering is narrowed down.

  However, by providing the slit 211 on the side surface of the nozzle 209, air is sucked from the slit 211 as shown by the broken line arrow in FIG. 6, so that it is possible to prevent the generation of circulating vortices in the nozzle 209. As a result, the diffusion range of the fine mist can be expanded, and the fine mist can be supplied almost uniformly over a wide area in the vegetable compartment 105, and humidification necessary for maintaining freshness can be performed.

  As described above, in the second embodiment, by providing the slits 211 on both side surfaces of the nozzle 209, the circulation vortex that limits the scattering direction of the fine mist in the nozzle 209 can be prevented, and fine particles can be dispersed over a wide range. Humidity necessary for maintaining freshness can be stably supplied by supplying mist into the storage chamber, and the freshness of food can be maintained over a long period of time.

  In the third embodiment, the slits 211 that are openings are provided on both side surfaces of the nozzle 209. However, by providing the slits 211 only on one side surface of the nozzle 209, the air flow in the nozzle 209 is reduced on both sides. Therefore, it is possible to control the scattering direction of the fine mist.

  Furthermore, by making the width, position, and height of the slit 211 on the side surface of the nozzle 209 non-uniform on both sides, the air flow in the nozzle 209 is different on both sides, so the direction of fine mist scattering can be controlled. become.

  In the third embodiment, the same effect can be obtained even if a slit that is an opening is provided on a ceiling surface or an inclined surface that is a wall surface of the nozzle 209.

  Furthermore, although the atomizing device is a Langevin type ultrasonic atomizing device, a mist can be sprayed, for example, a disk type ultrasonic atomizing method or an electrostatic atomizing device may be used.

  In each of the above embodiments, water is used as a mist for maintaining a high-humidity environment in the vegetable compartment in the refrigerator, but the water may have a slightly different property depending on the application. For example, a liquid obtained by melting a substance having a use (function) required for water, such as antioxidant water, ionic water, sterilized water, or the like can be used.

  As described above, since the refrigerator according to the present invention can stably spray mist into the storage chamber, it can be used not only for household refrigerators, but also for commercial refrigerators, food storage, cold storage vehicles, and incubators. As described above, the present invention can also be applied to uses such as medical equipment for maintaining the storage chamber in a constant humidity environment.
